dc Floating Voltage: Output terminals can be floated up
to ±60 Vdc maximum from chassis ground
Remote Sensing: Up to half the rated output voltage can be
dropped in each load lead. The drop in the load leads sub-
tracts from the voltage available for the load.
Command Processing Time: Average time required for the output
voltage to begin to change following receipt of digital data is
20 ms for power supplies connected directly to the GPIB
Modulation: (analog programming of output voltage and current):
Input Signal: 0 to –5 V for voltage, 0 to +5 V for current
Input Impedance:30 kΩ or greater
ac Input (47 to 63 Hz): 180 to 235 Vac (line-to-line, 3 phase), 27.7 A
rms maximum; 360 to 440 Vac, 14.3 A rms maximum
(maximum line current includes 5% unbalanced phase voltage
condition.) Output voltage derated 5% at 50 Hz and below
200 Vac.
Input Power: 7350 VA and 6000 W maximum; 160 W at no load
GPIB Interface Capabilities: SH1, AH1, T6, L4, SR1, RL1, PP0,
DC1, DT1, E1, and C0. IEEE-488.2 and SCPI command set.
Size: 425.5 mm W x 220 mm H x 675.6 mm D (16.75 in x
8.75 in x 26.6 in) See page 57 for more details
Weight: Net, 51.3 kg (113 lb); shipping, 63.6 kg (140 lb)
Warranty Period: Three years
